Abstract

I have expropriated the title of Prichard's 1912 paperl because, I too answer his question
affinnatively. But the mistake I detect is not the one Prichard thought he had uncovered, and his
article is a classic example of the mistake I propose to discuss. It is to believe, as some moral
philosophers still appear to do, that moral philosophy has a special domain or special method that
distinguishes it in some important way from sociology, anthropology, psychology and economics. I
shall argue that these moral philosophers are misled by the "philosophical" vocabulary they use.
